Show you what human chorionic gonadotropin is (I)！

　　Human chorionic gonadotropin is a glycoprotein secreted by trophoblast cells of placenta. The composition of human chorionic gonadotropin is composed of two glycoproteins, which are alpha and beta dimers respectively. The molecular weight of human chorionic gonadotropin is 3670.

　　Women today use the word human chorionic gonadotropin, but it often appears on hospital blood tests. Human chorionic gonadotropin (HCG) has great reference value in the diagnosis and differentiation of pregnancy, trophoblast cell tumor and other diseases. It is also necessary for us ordinary people to understand human chorionic gonadotropin.

　　Human Chorionic Gonadotropin (HCG) is short for Human Chorionic Gonadotropin. HCG has the functions of FSH and LH, which maintain the life span of the corpus luteum and stimulate the formation of progesterone. HCG is detected in urine when it enters the mother's blood six days before and after fertilization of the fertilized egg. During the first 3 months of pregnancy, serum and urine HCG levels increase rapidly, doubling on average between one and three days. In addition, HCG levels peak around the 10th week of gestation and fall to a moderate level in the fourth month of gestation, which continues until the end of the pregnancy. Clinically, the rapid and slow growth of HCG needs our attention. The detection of chorionic gonadotropin is very important for the diagnosis of early pregnancy.
